About

I'm a Backend Developer at Deloitte USI, building scalable microservices and cloud-native backend systems with a focus on performance, reliability, and clean architecture.

My experience spans designing scalable REST APIs, architecting microservices, developing event-driven and asynchronous workflows, integrating databases and third-party services, and building enterprise healthcare solutions used by 50+ hospitals.

I enjoy designing distributed systems, solving complex backend challenges, and building reliable applications that are scalable, maintainable, and production-ready.
